SPECIFICATION forming part of Letters Patent N0.34:4,049, dated Tune 22,1886.

Application filed July 28, 1885. Serial No. 172,918. (Model.)

To all whom t may concern,.-

Be it known that I, JAMES A. KIRBY, residing at Chicago, in the countyof Cook and State of Illinois, and a citizen of the United States, haveinvented a new and useful Improvement in Car-Door Seal-Locks, of whichthe followingis a full description, reference being had to theaccompanying drawings, in whichp Figure l is a perspective view showingthe seal-lock in position; Fig. 2, a longitudinal section showing theparts in locked position; Fig. 3, a longitudinal section showing theparts in unlocked position; Fig. 4, a perspective view of the casingstrap or loop and spring catch or dog; Fig. 5, a perspective of theslide or keeper; Fig. 6, a perspective of the cap; Fig. 7, a perspectiveof the dog or catch.

This invention is primarily designed for sealr ing the doors oftransportation-cars, but can be applied to and used for locking otherreceptacles, which it is desirable to have effectually guarded againstbeing tampered with, and has for its object to produce a seal-locksimple in construction, readily locked, and which cannot be unlockedwithout having such performance at once disclosed 5 and its natureconsists in the several parts and combination of parts hereinafterdescribed, and pointed out in the claims as new.

In the drawings, Arepresents a shell made of brass, malleable iron,steel, or other suitable material, which can be cast or otherwise formedinto shape Eto have a bottom part, a, side walls, c', and end walls, aa3, and, as shown, the juncture of the bottom a to the end wall, a?, isout away, so as to leave an opening, b, and the face of the end wall,a3, is provided with astud or pin, b, either formed therewith orpermanently secured therein or thereto.

Brepresents a strap or loop of steel or other material, one end of whichenters the opening b,and is rmly secured to the inner face of the bottomce by brazing, riveting, or otherwise, and the other end is providedwith a hole, b', to receive the pin or stud b/,to connect this end withthe casing.

C represents a slide or keeper formed of a :metal plate, andcorresponding in length, or

nearly so, to the length of the casing A as a whole. The inner face of Cis provided with a catch, c, and its acting end C, as shown, is providedwith a notch or recess, c', to receive the stud or pin b, and this endC', as shown, is of less width than the body of the slide,and its edgesrest on shoulders c3, formed in the face of the end a3, and the face ofthe end a3, as shown, is cut away between the shoulders to leave a spacefor the end of the strap or loop B beneath the end C. The body ofthekeeper C is provided with a longitudinal slot, C, as shown in Fig. 5,and the outer face of the keeper has a cross-piece, C3, which,'as shown,is of the same width as the casing,` and this cross-bar C3, as shown, iscut away adjacent to the slot C, so as to leave aspace, C, to allow thekeeper to move.

D represents a cap or plate of metal, having, as shown, a hole oropening, d, and having an end, D', provided with an opening, d', toallow the end of B to pass over the pin orstud b, and having an end, D,with a guide, d, to enter the slot C and maintain the slide or keeper Cin a straight line of travel.

E represents a catch or dog located inside of the casing A ,beneath theslide or keeper C, and having its end e arranged to engage the catch c,when the slide or keeper Cis proj ected, and prevent the withdrawal ofthe slide or keeper until the end e is disengaged from the catch c. Theacting end of this dog or catch is cut away,so as to form a second stopto limit the withdrawal of the slide or keeper in the form ofconstruction shown, and, as shown, the tail end E of the dog or catch isprovided on each side with a trunnion, e, which drop into rests e3 onthe inside face of the walls c, so as to give the dog or catch a pivotalsupport by which its free end can be made to rise and fall. The body ofthe dog or catch on the outer face is provided with a projection, e',which, when the parts are together, projects into the hole d of the capor plate D.

F represents a spring, one end of which, as shown, is secured around apin, f, on the end c, and the other end engages the tail end of the dogor catch E, and bears thereon to hold the free end e in contact with theslide or s i l 344,049`

keeper, except when such end is forced away, by pushing inthenprojection e. As shown, the end of the spring F, around the pin f,is in a recess in the endpbar, c, and is held therein by the guide d onthe cap or plate D, which,as shown, also enters this recess, thepin fpassing into a hole, f', through the `guide d and end D, and, as shown,the end a3 at each side has a pin, f, which enter holes]C3 in the 13 endD. The pins ff and holes ff3 furnish the means for securing the cap orplate D to the casing, and the attachment is made secure by rivetingdown or upsetting the ends of the pins f f, so that they act as rivets,and when together the slide or keeper C isfree to move between thecasing and cap or cover. G represents a plate of glass or other fragilematerial having a backing, G', of paper or other material, with lettersand numerals 2o to indicate the sea-ling of the article with which thelock is used. This seal, as shown, rests on supports g g', and is heldin place by catches g g3, the catches g3 being formed on the edge ofcross-bar C3, and being movable therewith to allow of the insertion andlock* ing of the seal, and, as shown, the catches are continued in ribson the side of the crossbar to give additional strength.

H represents a receptacle for the seal,

' 3o formed with or suitably secured to the cap or plate D. As shown,the receptacle is formed with side walls, h, end wall, h', and end bar,h, and theend wall, h', has on its edge the catches g, while the endbar, h, has at its ends the supports g', and the other end wall isformed, when the parts arelocked together, by the cross-bar C3, so thatwhen the seal is in place it is completely inclosed by the walls h h,h', and C3 resting on the supports gg and 4o secured by the catches gg3, and when in place access cannot be'had to the projection e todisengage the dog or catch E until the seal is broken.

I represents -a hasp fitting over a staple, J', through which the strapor loop B passes to secure the door-lid or other article to be secured.These parts I J are simply shown to illustrate the use of the seal-lock.

The parts forming thelock are put together Y5o by securing the strap orloop B at one end firmly to the casing, to have its free end engage withthe pin b. The catch or dog E is dropped into the casing with itstruniiions c resting in the blocks e3,- the spring is placed in positionto have its free end engage the tail E of the dog or catchV E, with itsother end resting on the end wall, a,- the slide or keeper Gis droppedinto place with its acting end resting on the ledges c, and its tail endon 6o the end wall, a, with the body ofthe dog E in the slot C, and thenthe cap or plate D is dropped onto the pins ff, and the pins riveteddown,securing the several parts together, so that the slide or keeper Cis free to move when disengaged from the catch E.' The lock is thenready for use 5 and in use for locking and sealing purposes, the strapor loop B is passed through the staple or eye or other receiver on thearticle to be locked and sealed. The slide or keeper C being withdrawn,a seal is placed in the receptacle H, the free end of the strap or loopis passed over the pin b", and the slide or keeper advanced to have itsacting end pass over the free end of the strap or loop, and by this samemovement the catches g3 are advanced to lock the seal in place; and whenthe keeper is advancd the dog or catch E, by the action of the' springF, is thrown behind the catch c, its free end engaging such catch andlocking the keeper 30 against withdrawal until the end e of the catch isdisengaged from the catch' c, and this can only be done by breaking theseal and disengaging the catch or dog by pressing on the projection e,by which means it will be seen that in case of unlocking, such unlockingwill be disclosed by the broken seal.

The lock and seal can be used on cars, package-chests, safes, mail-bags,and other receptacles which it is desired to lock and'go seal securely,and when opened by the propery Yparty the lock is not injured forfurther use,

as the seal only isr broken, so that the lock can be used again byinserting a new seal.

The lockV is very simple, will not be easily broken, and if broken, canbe easily repaired, and cannot be unlocked readily, except by breakingthe seal, and in use the parts cannot be released by a sudden blow, asthe keeper or slide is independent of the attaching casing and strap,and by having the strap or loop attached to the casing, pulling on thecasing does not affect the slide or keeper C, which is held by the catchor dog E.

Where the looped strap is secured entirely to the slide or keeper, asheretofore, a sudden blow on the lock will sometimes dislodge or throwthe slide, so that the looped strap can be unfastened. This is avoidedby attaching the looped strap at one end to an im- 11o movable part ofthe lock-case, and having its other end engaging a stud, also on thelockcase, sovthat the slide or keeper is not directly attached in anymanner to the strap.

What I claim as new, and desire to secure 1r 5 by Letters Patent, is-

l. The combination of the lock-case A, having the attached stud or pinb, and the slide or keeper C, with the looped strap rigidly attached atone end to an immovable part of x2o` the lock-case, and at the other endadapted to engage the stud or pin, substantially as described.

2. A casing, A, having a stud or pin, b, and loop or strap B, fastenedat one end securely to the casing, in combination with a slide, 0,.having catch c and spring dog E, for holding the free end of the strapwhen on the stud or pin, substantially as and for the purposesspecified. I 13o 3. A casing, A, strap or loop B, fastened at one endsecurely to the casing, and stud or 344,64@ i ii pin b, in combinationwith the slide 0,11avprojection e', and cap D, having opening ci', ingcatch c, and spring-Catch E, having prosubstantially as and for thepurposes speei- 1o jection e', substantially as and for the purposefied.

specied.

4. A casing, A, having a stud or pin, b, strap or loop B, fastened atone end securely to the casing, and slide C, having catch c, incombination with the spring-catch E, having JAMES A. KIRBY.
